Sam's grandfather is over 70 years old. He was a teacher fifteen years ago. He could read and draw when he was seven years old. But he couldn't draw. He likes reading and he likes reading newspapers for the news. Fifteen years ago, he often read newspapers after supper. But now he doesn't. He often reads e-books. And he also doesn't often use a tele-phone. He uses a mobile phone to call his friends. He listened to the radio then, now he watches TV and works on the Internet.
